Diagnosis.

This species can be distinguished from all other similar Cicindelidia by its dark green-violet abdominal venter with the two apical segments dull orange or orange-brown, a brassy-cupreous head and pronotum with metallic blue reflections in sulci, small shallow subsutural foveae present in most individuals, and microserrate elytral apices. It inhabits rocky upland soils in ponderosa pine forests above 2000 m (Fig. 1). Cicindelidia sedecimpunctata (Klug, 1834) has an entirely orange-red to orange-brown abdominal venter, a more uniform dull brown dorsal coloration, and lacks apparent subsutural foveae. It also differs from the new species by inhabiting muddy ground at nearly any elevation. Cicindelidia nebuligera (Bates, 1890) has dark elytral infuscations that surround the middle band, and lacks elytral apical microserrations. It may be found in similar habitats, but is apparently allopatric with the new species and does not appear to be restricted to elevations above 2000 m.

Description.

Small to medium sized Cicindelidia . Body (Figs 2-5) length 7.90-10.50 mm, mean ♀ 9.7 mm, mean ♂ 9.0 mm. Head (Figs 6-7) slightly wider than pronotum, width 2.3-2.7 mm, brassy-cupreous red with metallic blue and cupreous reflections present in sulci, all head portions glabrous except for 2 supraorbital setae next to each eye. Frons concave in median area especially in male, bulging towards slightly convex near anterior margin, clearly delimited from clypeus, gradually blending into vertex. Frons surface with distinct longitudinal striae especially in lateral areas bordering eyes, vermiculate-striate in median area. Vertex dark brassy colored, slightly convex, with surface indistinctly finely vermiculate, posterior areas with cupreous-olive lustre. Genae bright polished copper with deep longitudinal striae abruptly ending at border of vertex. Clypeus cupreous blending to blue along borders, irregularly wrinkled to finely vermiculate. Labrum with 6 setae, ochre-testaceous with a thin dark brown to black border; female labrum rather long, length 0.60-0.90 mm, width 1.3-1.6 mm, with single median tooth; male labrum short to medium, length 0.45-0.80 mm, width 1.2-1.7 mm, shape varies from nearly straight across anterior edge with only slightly protruding median tooth to an unusual slightly notched median edge (see holotype). Mandibles medium-sized, ochraceous in male, dark ochraceous with metallic gold, green and black reflections in female, teeth of both sexes dark testaceous along edges. Maxillary palpi dark testaceous with metallic reflections; apical segment usually darker than sub-apical segment. Labial palpi in male ivory to pale yellow-ochre in male with dark metallic green to violet apical segment, in female entirely dark testaceous with metallic reflections throughout. Antennae normal length, reaching humerus to basal third of elytron, slightly longer in male than female; scape dark testaceous to black with metallic reflections of cupreous, gold, and violet, with a single apical seta; pedicel dark testaceous with metallic reflections of cupreous, gold, and violet, lacking any setae; flagellum dark testaceous, antennomeres 3-4 with metallic cupreous and violet reflections, with ring of apical setae and additional sparse setae throughout, antennomeres 5-11 dull textured without metallic reflections and possessing erect setae in apical rings only, covered with fine pubescence throughout.

Thorax. Pronotum 1.70-2.50 mm in width, slightly polished with metallic finish, brassy-cupreous with metallic blue or blue-green sulci, slightly wider than long, nearly trapezoidal in shape and widest near anterior margin, width to length ratio 1.2 to 1.3, setae sparse and present along lateral third of dorsal surface; disc finely rugose to vermiculate with thin but distinct median line and deeply impressed sulci; notopleural sutures clearly defined, not visible from dorsal view; proepisternum bright polished copper with gold and green reflections more ventrally, abruptly transitioning to blue-violet on ventral third and posterior third, in male setae present throughout surface of proepisternum, but in female setae are typically sparsely present only along ventral third and along anterior margin; all other ventral segments of thorax are glabrous, dark blue-violet to black with greenish reflections. Elytra elongate, 5.1-6.7 mm length, shape similar in both sexes, but slightly wider in female, especially toward apical third; sutural spine small to nearly absent, fine microserrations present on elytral apices (Fig. 8), extremely fine to nearly indistinct in some individuals; elytral dorsal surface relatively flat, not markedly convex, texture dull throughout with slight metallic sheen near pronotal base in a some individuals, elytral coloration mostly a dull cupreous brown color, under magnification this color is comprised of the pointillistic mixing of mostly cupreous ground color with many small patches of dark blue-violet bordered in green; subsutural foveae are present, but nearly indistinct in a small percentage of individuals; elytral maculations white, and consist of a small humeral and posthumeral spot, a moderately short middle band which does not touch the margin and with “knee” and “foot” regions connected with a thin but complete line, an isolated marginal spot between the middle band and apical lunule, and an apical lunule comprised of a subapical spot that is broken from the thin apical line; epipleura dark blue-violet to black.

Legs. Procoxae and mesocoxae dark metallic green to black, covered in dense setae; metacoxae dark metallic green to blue-violet to black, with a single apical setae present; trochanters glabrous, dark green to violet-black; femora dark metallic green with blue-violet reflections near the insertion of the tibia, femoral surface with rows of erect white setae dorsally and ventrally; tibiae violet to dark cupreous with dark green reflections near the apices, clothed with white setae that are sparser and shorter than those of the femora; tarsi violet with blue reflections dorsally, first three dilated protarsomeres in male with dense greyish-white setal pad.

Abdomen. Ventrites 1-4 dark violet with strong metallic greenish reflections throughout most surfaces, dark orange to testaceous coloration along lateral edges in some individuals, setae present mostly along lateral third of each ventrite; ventrites 5-6 orange to dark orange-testaceous throughout, setae present along lateral margins, but often abraded.

Reproductive structures. Aedeagus (Fig. 9) elongate, widest in middle, length 3.40-3.60 mm, width 0.65-0.75 mm, slightly arcuate in ventral view, apical portion produced into a narrow tip with a slight hooklike projection; internal sac and sclerites prominent in cleared aedeagus and visible both ventrally and laterally. Ovipositor (Fig. 10) deeply notched and possessing two heavily sclerotized bifurcated hooks ventrally, setae present especially along lateral margins and near base of hooks.

Etymology.

This new Cicindelidia is named after the first author’s wife, Melissa, for her constant support, love, and friendship.

Distribution and habitat.

Cicindelidia melissa is currently known from northwestern Durango, western Chihuahua, eastern Sonora, and southeastern Arizona. All known occurrences are from forested hillsides and trails above 2000 m. Typical habitats contain rocky substrates derived from limestone and/or rhyolite, with forest cover generally dominated by Ponderosa pine. This species is mostly active following monsoon rains, but frequents upland areas and is not closely associated with muddy or riparian microhabitats.
